Point of care blood gas analyzer: Overview, Uses and Top Manufacturer Company

Introduction

A Point of care blood gas analyzer is a bedside (or near-patient) clinical device used to measure blood gas and related critical-care parameters from a small whole-blood sample. In practice, it helps teams rapidly assess oxygenation, ventilation, and acid–base status—often when minutes matter and decisions must be made before a central laboratory result would realistically return.

In modern hospitals and many ambulatory or emergency settings, this medical equipment sits at the intersection of clinical urgency and operational reliability. It is used in intensive care units (ICUs), emergency departments (EDs), operating rooms (ORs), neonatal and pediatric areas, and sometimes in step-down units, transport environments, and dialysis units—wherever rapid physiologic assessment is needed and workflows support safe point-of-care testing (POCT).

This article is written for two overlapping groups:

• Learners (medical students, residents, and trainees) who need a clear mental model of what the device measures, how results are generated, and how common errors happen.
• Hospital administrators, biomedical engineers, procurement teams, and operations leaders who must ensure the device is appropriately selected, implemented, maintained, and governed so that results are reliable and patient safety risks are controlled.

You will learn what a Point of care blood gas analyzer does, when it is typically used (and when it may be inappropriate), what is needed before starting, how basic operation generally works, how to reduce safety risks, how to interpret outputs thoughtfully, what to do when something goes wrong, how to clean the device safely, and how the global market environment differs by country.

What is Point of care blood gas analyzer and why do we use it?

Clear definition and purpose

A Point of care blood gas analyzer is a POCT medical device designed to analyze a fresh whole-blood sample close to the patient and quickly report values related to:

• Acid–base status (for example, pH and calculated bicarbonate).
• Ventilation (commonly represented by carbon dioxide measurements).
• Oxygenation (commonly represented by oxygen measurements).
• Additional parameters depending on the model (such as electrolytes, lactate, hemoglobin, and co-oximetry fractions).

The core purpose is speed with clinically actionable data at the bedside, while maintaining acceptable analytical performance through built-in calibration routines, quality control (QC) features, and controlled consumables (varies by manufacturer).

Common clinical settings

You will most often see a Point of care blood gas analyzer in settings where rapid physiologic assessment is a frequent need and where the cost and governance of POCT can be justified:

• Emergency departments: rapid triage of respiratory distress, shock states, or altered mental status.
• ICUs: ventilator management, hemodynamic instability evaluation, and monitoring of evolving critical illness.
• Operating rooms and post-anesthesia care units (PACUs): perioperative ventilation/oxygenation and acid–base monitoring.
• Neonatal and pediatric units: small-volume sampling and rapid feedback for respiratory and metabolic disturbances.
• Respiratory care areas: assessment during escalation or de-escalation of respiratory support.
• Transport and remote care (in some systems): when central lab access is limited or too slow (workflow and regulatory constraints vary).

Key benefits in patient care and workflow

A Point of care blood gas analyzer can support care and operations by:

• Reducing time-to-result compared with sending samples to a central laboratory (especially after-hours or during surges).
• Improving decision workflow when results are needed to guide immediate actions (for example, adjustments to ventilation strategies under supervision and local protocol).
• Lowering pre-analytical delay when the analyzer is physically near the bedside and samples can be tested quickly.
• Supporting high-acuity throughput in areas like ED resuscitation bays and operating rooms.
• Enabling small sample volumes in many systems (useful in neonatal/pediatric settings), though sample requirements vary by manufacturer and cartridge type.

Operationally, speed is only valuable if results are reliable, properly attributed to the correct patient, and integrated into documentation. That is why POCT governance, operator competency, and device connectivity (to the electronic health record, EHR) matter as much as the analyzer itself.

Plain-language mechanism: how it generally functions

While the internal design varies, most blood gas analyzers use one or more of these general measurement principles:

• Electrochemical sensors to measure pH and partial pressures of gases (oxygen and carbon dioxide).
• Ion-selective electrodes (ISEs) for electrolytes (such as sodium, potassium, ionized calcium) in models that include electrolyte testing.
• Optical methods for certain hemoglobin species in devices with co-oximetry capabilities (varies by manufacturer).

Many Point of care blood gas analyzer systems are cartridge-based or use cassettes. The cartridge/cassette may contain sensors, calibrants, and fluidic pathways designed to minimize operator steps and stabilize performance. The device typically performs self-checks and some form of calibration/verification at defined intervals (automatic or prompted), but the details—what is automatic, what is user-triggered, and what consumables are required—vary by manufacturer.

How medical students typically encounter or learn this device

In training, learners usually meet blood gas testing in two parallel ways:

1. Physiology and pathophysiology teaching: interpreting pH, carbon dioxide, oxygen, and compensation patterns as part of respiratory and renal physiology.
2. Clinical rotations: seeing blood gas results used in real-time in the ED, ICU, OR, or neonatal unit.

A common educational gap is that learners may focus on interpreting numbers while overlooking the pre-analytical and operational realities—sample type, timing, air exposure, anticoagulant effects, patient identification, and device QC status. Understanding the Point of care blood gas analyzer as both a clinical tool and a piece of hospital equipment helps bridge that gap.

When should I use Point of care blood gas analyzer (and when should I not)?

Appropriate use cases (typical examples)

Use of a Point of care blood gas analyzer is generally most appropriate when rapid information is needed to support time-sensitive evaluation or monitoring, such as:

• Acute respiratory distress where oxygenation/ventilation status needs rapid assessment.
• Ventilated patients when timely feedback is needed for ventilation and acid–base status (under supervision and local protocol).
• Perioperative monitoring during complex surgery or in unstable patients where rapid trends matter.
• Shock or suspected tissue hypoperfusion, where lactate or acid–base information may be part of the clinical picture (availability varies).
• Severe metabolic derangements where rapid acid–base and electrolyte information is needed (electrolytes vary by model).
• Neonatal/pediatric monitoring where small-volume sampling and quick turnaround may reduce repeated phlebotomy burden (workflow dependent).
• Situations where central lab turnaround time is unpredictable due to transport constraints, high volumes, or limited staffing.

These are examples of operationally and clinically plausible use cases; actual indications should follow local policy, clinical supervision, and the manufacturer’s intended use.

When it may not be suitable

A Point of care blood gas analyzer may be a poor fit when:

• The situation is non-urgent and central lab testing provides adequate turnaround with stronger analytical governance.
• A trained operator is not available, or competency cannot be confirmed (for example, no operator ID access, lapsed competency).
• Quality controls are not in compliance, the analyzer is out of service, or required maintenance is overdue.
• Consumables are expired or improperly stored, or the supply chain is unreliable (temperature excursions can matter; varies by manufacturer).
• Connectivity or documentation pathways are unreliable, increasing the risk of results not being captured in the patient record.
• The sample cannot be collected and handled correctly (for example, likely contamination, prolonged delay, unknown sample type).
• The test required is outside the device’s menu or intended use (for example, assuming a derived value is directly measured when it is calculated).

In these situations, delaying a decision to obtain a more reliable result (or confirming a surprising result with an alternate method) may be safer than acting on potentially compromised data.

Safety cautions and contraindications (general, non-clinical)

This section is informational and not medical advice. Major cautions with Point of care blood gas analyzer use are often about process, not the analyzer itself:

• Blood exposure risk: handling fresh blood increases the risk of bloodborne pathogen exposure; use appropriate personal protective equipment (PPE) and sharps safety.
• Needlestick and sharps hazards: sample collection and disposal must follow facility policies.
• Patient misidentification: incorrect patient association is a high-impact, preventable error; barcode workflows and two-identifier checks matter.
• Sample integrity risks: air exposure, clotting, dilution, or delays can distort results and lead to inappropriate clinical decisions.
• Overreliance on a single number: blood gas results are a snapshot; clinical correlation and trend awareness are essential.
• Environmental limitations: extreme temperature, humidity, vibration, or power instability can affect performance (varies by manufacturer).

Always defer to local policies, supervision requirements, and manufacturer instructions for use (IFU). If there is a mismatch between the result and the clinical picture, pause and verify before acting.

What do I need before starting?

Safe and reliable use of a Point of care blood gas analyzer depends on more than switching the device on. It requires the right environment, consumables, governance, and trained people.

Required setup, environment, and accessories

Common prerequisites include (exact items vary by manufacturer and care area):

• Stable power (and sometimes backup power/UPS depending on risk assessment).
• A clean, designated work surface near the patient care area but protected from splashes.
• Environmental conditions within the device’s specified temperature and humidity range (varies by manufacturer).
• Approved consumables: cartridges/cassettes, QC materials, and any required calibration items (model dependent).
• Sample collection supplies appropriate to local practice: heparinized syringes or capillary devices, needles, alcohol wipes, gauze, labels/barcodes, and sharps containers.
• PPE: gloves at minimum, and additional PPE as required by infection prevention policy.
• Waste handling supplies: biohazard waste bins, spill kits, and disinfectant products approved for the device surfaces.
• Connectivity accessories: network connection, barcode scanner, printer (if used), and integration middleware (varies by facility).

Training and competency expectations

Point-of-care testing is typically governed by a formal competency program. Common expectations include:

• Initial training on device operation, sample handling, QC processes, and documentation.
• Competency assessment at onboarding and at defined intervals (frequency varies by facility and region).
• Operator access controls such as login credentials or badge scanning to prevent untrained use (varies by manufacturer and policy).
• Understanding of limitations: what the device measures vs calculates, and how pre-analytical errors arise.

For trainees, supervision requirements may be explicit: you may be permitted to perform testing only when a trained clinician or nurse confirms the workflow and documentation steps.

Pre-use checks and documentation

Before running patient samples, many facilities require:

• Visual inspection: check for damage, leaks, missing covers, or contamination.
• Consumable checks: correct cartridge type, within expiration date, stored appropriately, and at the correct temperature per IFU.
• QC status review: confirm required QC has been performed and is in range (facility policy).
• Calibration/self-test confirmation: ensure the device indicates readiness and no lockout states are active.
• Device logs: verify maintenance status, error history, and cleaning documentation if your facility tracks these at the unit level.

Documentation expectations often include patient identifiers, operator ID, time of sample collection, time of analysis, and any notes about sample type or collection conditions (format varies by facility).

Operational prerequisites: commissioning, maintenance readiness, consumables, and policies

From an operations perspective, safe use begins before the device arrives on the unit:

• Commissioning: acceptance testing, configuration, connectivity setup, and verification that the device matches procurement specifications.
• Maintenance readiness: defined preventive maintenance schedules, assigned owners, and a plan for downtime coverage.
• Consumable management: par levels, storage conditions, lot tracking, and contingency planning for supply disruptions.
• Policies: POCT governance (often via a POCT committee), QC frequency, operator competency rules, critical value communication, and incident reporting pathways.
• Data management: how results flow into the EHR, who resolves interface errors, and how corrections/amendments are handled.

Roles and responsibilities (clinician vs. biomedical engineering vs. procurement)

A Point of care blood gas analyzer is hospital equipment with shared accountability:

• Clinicians and nurses typically collect samples, run tests, validate patient identification, and act on results within their scope and protocols.
• Laboratory/POCT leadership (or a POCT coordinator) often owns QC programs, proficiency testing (where applicable), policy setting, training frameworks, and oversight of analytical performance.
• Biomedical engineering typically manages preventive maintenance, repairs, safety checks, device fleet standardization, and coordination with vendors for service.
• Procurement and supply chain manage contracts, pricing models (instrument vs consumables), inventory reliability, and vendor performance.
• IT/informatics supports connectivity, middleware, cybersecurity, user access, and EHR result routing.

Clear ownership prevents the common failure mode where “everyone uses it” but no one is accountable for uptime, QC compliance, and connectivity.

How do I use it correctly (basic operation)?

Workflows differ across models, but most Point of care blood gas analyzer operations share a common backbone: verify the patient, collect a suitable sample, run the sample promptly, review plausibility, and document correctly.

Universal workflow (high-level)

A commonly universal sequence looks like this:

1. Confirm the order or clinical indication according to local policy (who can order/run POCT varies).
2. Perform patient identification using required identifiers and/or barcode scanning.
3. Prepare the analyzer: verify readiness, correct cartridge type, and QC status.
4. Collect the sample using an approved method and container.
5. Remove obvious air and mix the sample as appropriate to local protocol and IFU.
6. Run the sample promptly to reduce time-related changes (exact timing requirements vary).
7. Review results for plausibility in the clinical context and check for device flags.
8. Document and communicate results per policy, including critical results escalation pathways.
9. Dispose of sharps and biohazard waste and clean/disinfect high-touch surfaces as required.

Sample collection and handling (general principles)

This is informational, not procedural medical advice. Key sample integrity principles include:

• Use the correct sample type (arterial, venous, or capillary) as intended by the test and local protocol; mislabeling sample type is a common error.
• Use appropriate anticoagulation if required; incorrect heparin use can dilute or alter certain measurements (details vary by practice and device).
• Avoid contamination from IV fluids, heparinized lines, or inadequate discard volumes when drawing from lines (facility policies differ).
• Minimize air exposure: air bubbles can change oxygen and carbon dioxide values and can affect derived parameters.
• Avoid delays: ongoing cellular metabolism can change results over time; prompt analysis reduces this risk.
• Mix gently but thoroughly to prevent microclots and ensure a representative sample.

If the sample appears clotted, hemolyzed, or compromised, do not assume the analyzer will “fix it.” Many errors originate before the sample ever enters the device.

Running the test (typical steps)

Although details vary by manufacturer, typical steps include:

• Log in (operator ID, badge, or password) if required by the POCT governance setup.
• Select patient and test using barcode scanning or manual entry (manual entry increases misidentification risk).
• Insert the cartridge/cassette or confirm it is loaded and recognized.
• Introduce the sample into the cartridge or sample port per IFU (do not force connections).
• Wait for analysis while the device performs measurement and internal checks.
• Review on-screen flags: many systems display warnings for sample problems (for example, suspected air, clot detection, sensor issues) or QC lockouts (varies by model).
• Print or transmit results to the EHR/LIS (laboratory information system) as configured.

Typical settings and what they generally mean

Some settings commonly encountered include:

• Units (mmHg vs kPa, mmol/L vs mEq/L): ensure the clinical team is accustomed to the displayed units.
• Sample type selection: arterial/venous/capillary; selecting the wrong type can affect reference interpretation and may affect some calculations.
• Temperature correction: some workflows allow entry of patient temperature; whether temperature-corrected values are used clinically varies by local policy and clinician preference.
• Reference ranges and flags: these may be configurable; do not assume a flag equals a diagnosis.
• Connectivity mode: online/offline; offline operation may require manual transcription, increasing risk.

If you are rotating between units, do not assume all analyzers are configured the same way; configuration is part of the local governance system.

How do I keep the patient safe?

Patient safety with a Point of care blood gas analyzer depends on controlling risks in four domains: correct patient association, safe sampling, reliable analysis, and safe communication.

Safety practices and monitoring

Key safety practices include:

• Two-identifier patient verification before sampling and before result entry/acceptance.
• Closed-loop labeling: label at the bedside and avoid “label later” practices.
• Sample-to-result time awareness: record collection time when required; interpret cautiously if delays occurred.
• Trend awareness: a single result should be interpreted alongside vital signs, clinical exam, and prior results when available.
• Clear escalation pathways for critical results: who must be notified, how quickly, and how it is documented (policy-driven).
• Avoiding duplicate testing: unnecessary repeated sampling increases iatrogenic risk and workload; stewardship is part of safety.

Alarm handling and human factors

Many analyzers provide alarms or lockouts for:

• QC failures
• Expired or incorrect cartridges
• Calibration or sensor issues
• Temperature out of range
• Connectivity errors

Human factors matter: in a noisy ED or during a resuscitation, it is easy to acknowledge an alarm without understanding it. Safer practices include:

• Stop-and-read: pause to read the full message, not just the headline.
• Do not bypass lockouts unless policy explicitly allows and you understand the risk.
• Use checklists during high-acuity moments (sample integrity, patient ID, QC status).

Risk controls, labeling checks, and incident reporting culture

A mature POCT program treats mislabels, QC breaches, and surprising results as learning opportunities:

• Labeling checks: confirm patient ID on the analyzer display matches the wristband and order.
• Result plausibility checks: if a result is clinically implausible, consider repeating with a fresh sample and/or confirming via central lab per local protocol.
• Documentation integrity: ensure results are captured in the EHR; “paper-only” results can be lost.
• Incident reporting: near misses (wrong patient selected, expired cartridge caught in time, sample spilled) should be reportable without blame to improve system design.

Always follow manufacturer guidance and local protocols; the safety envelope is created by both.

How do I interpret the output?

Interpreting a Point of care blood gas analyzer report is both a physiology exercise and a process-awareness exercise. The same number can be meaningful—or misleading—depending on sample type, timing, and collection conditions.

Types of outputs/readings (typical)

A blood gas report may include some or all of the following (device menus vary):

• Measured blood gas values: pH, partial pressure of carbon dioxide (often written as pCO₂), partial pressure of oxygen (often written as pO₂).
• Calculated/derived values: bicarbonate (HCO₃⁻), base excess/base deficit, total CO₂, and sometimes oxygen saturation estimates (depending on method).
• Electrolytes (if equipped): sodium, potassium, ionized calcium, chloride.
• Metabolites: lactate, glucose (availability varies by manufacturer and cartridge).
• Hemoglobin-related parameters: hemoglobin/hematocrit estimates and/or co-oximetry fractions (oxyhemoglobin, carboxyhemoglobin, methemoglobin) in models with co-oximetry.
• Flags and quality indicators: sample integrity warnings, error codes, QC status indicators.

A practical interpretation habit is to ask: Which values are measured vs calculated? Calculated values depend on assumptions and measurement inputs, so errors can propagate.

How clinicians typically interpret them (educational framing)

Clinicians often use a structured approach:

• Step 1: Check pH to identify acidemia vs alkalemia.
• Step 2: Review pCO₂ as a marker of ventilation contribution.
• Step 3: Review bicarbonate/base excess to assess metabolic contribution (remember many are calculated).
• Step 4: Review oxygenation metrics (pO₂ and/or saturation) in the context of the patient’s oxygen delivery settings and overall clinical picture.
• Step 5: Review lactate and electrolytes (if available) as supportive data in shock, metabolic derangements, or therapy monitoring.
• Step 6: Look for flags and pre-analytical clues: timing, sample type, and any device warnings.

For learners, the goal is not to “treat the number,” but to understand what the number represents and how confident you should be in it.

Common pitfalls and limitations

A Point of care blood gas analyzer is fast, but it is not immune to errors. Common pitfalls include:

• Sample type confusion: venous and arterial values differ; capillary sampling has its own limitations; wrong sample labeling can mislead interpretation.
• Air bubbles: can alter pO₂ and pCO₂ and therefore change derived values.
• Delay to analysis: cellular metabolism continues after sampling and can shift gases and pH.
• Heparin dilution or improper anticoagulant: can affect electrolytes and other analytes.
• Line draw contamination: residual flush solution or infusates can distort results.
• Temperature correction confusion: temperature-corrected values may differ from non-corrected; local policy varies on which to use.
• Analytical differences vs central lab: whole blood vs serum/plasma methods and different measurement technologies can yield systematic differences; trending within one method is often more meaningful than comparing across methods without context.
• Over-interpretation of single-point data: physiologic states change quickly; integrate with clinical assessment and repeat testing when indicated by protocol.

When results do not fit the clinical context, the safest next step is often to verify sample integrity, repeat appropriately, and/or confirm with an alternative method per local policy.

What if something goes wrong?

When a Point of care blood gas analyzer produces an error, an unexpected result, or an operational failure, the priority is to protect patients from acting on unreliable data and to restore safe service quickly.

Troubleshooting checklist (practical)

Use a structured checklist before escalating:

• Confirm patient selection and identifiers are correct (wrong-patient errors happen).
• Check device readiness: no lockouts, no active alarms, and correct cartridge type loaded.
• Verify consumable integrity: cartridge lot, expiration date, storage conditions, and package damage.
• Review QC status: were required QC checks completed and within range?
• Check sample quality: clotting, visible air, insufficient volume, delay since collection, or suspected contamination.
• Re-run using a new cartridge if the device indicates cartridge failure (do not reuse single-use consumables).
• If repeating, collect a new sample rather than reusing a compromised one.
• Confirm connectivity status if results are not transmitting (network outages can mimic device failure).
• Inspect for contamination or spills around the sample port and high-touch surfaces; clean per IFU.
• Read and record error codes exactly as shown; they are often essential for service support.

When to stop use

Stop using the device and follow your facility escalation pathway when:

• QC is out of range and cannot be resolved per policy.
• The device shows repeated measurement errors across multiple cartridges.
• There is visible damage, leakage, or evidence of internal contamination.
• The device cannot reliably associate results to the correct patient (scanner failure with no safe workaround).
• Results are repeatedly implausible and cannot be reconciled with repeat sampling and process checks.

When to escalate to biomedical engineering or the manufacturer

Escalate when the issue is likely device-related or requires authorized service:

• Persistent calibration failures or sensor errors.
• Hardware issues (touchscreen failure, sample pump malfunction, cartridge recognition faults).
• Recurrent connectivity/interface problems that require IT/middleware changes.
• Any event that may represent a device safety issue, including electrical hazards, smoke/overheating, or repeated incorrect outputs despite proper process.

Document the event according to policy, including operator ID, time, device serial/asset number, cartridge lot number (if relevant), and steps already taken.

Documentation and safety reporting expectations (general)

Good reporting protects future patients:

• Document what happened, what was done, and who was notified.
• Use your facility’s incident reporting system for misidentification risks, exposure events, or suspected incorrect results that could impact care.
• Preserve materials if requested (cartridge lot details, printed reports) per local policy and privacy requirements.

Infection control and cleaning of Point of care blood gas analyzer

Because it is used near patients and may be handled with gloved hands after blood sampling, a Point of care blood gas analyzer should be treated as potentially contaminated hospital equipment. Cleaning must protect both patients and staff without damaging sensors, seals, or touchscreens.

Cleaning principles (what matters most)

• Follow the manufacturer IFU: disinfectant types, contact times, and “do not use” lists vary by manufacturer.
• Use facility-approved products that match infection prevention policy and material compatibility.
• Clean then disinfect when visible soil is present; disinfectant efficacy drops when organic material is not removed.
• Avoid liquid ingress: do not spray directly into vents, ports, or cartridge bays unless IFU allows.
• Use appropriate PPE: gloves at minimum; add eye protection if splash risk exists.

Disinfection vs. sterilization (general)

• Cleaning removes visible soil and reduces bioburden.
• Disinfection uses chemical agents to inactivate microorganisms on surfaces; this is the typical requirement for external surfaces of POCT devices.
• Sterilization is a higher-level process intended to eliminate all forms of microbial life; it is generally not used for the external surfaces of electronic analyzers and is not appropriate unless the IFU explicitly describes a sterilization method (uncommon).

High-touch points to prioritize

Focus on surfaces that are frequently touched during operation:

• Touchscreen and buttons (if present)
• Barcode scanner window and trigger area
• Cartridge/cassette door handle or latch
• Sample port area and surrounding deck
• Side handles and power button
• Printer surfaces (if attached)
• Nearby work surface used for sample handling

Example cleaning workflow (non-brand-specific)

A practical, policy-aligned workflow often includes:

1. Perform hand hygiene and don gloves.
2. If visible contamination is present, wipe with a compatible cleaner first.
3. Wipe high-touch surfaces with an approved disinfectant wipe, keeping surfaces visibly wet for the required contact time (per product label and IFU).
4. Do not allow fluid to pool near openings; use controlled wiping motions.
5. Allow surfaces to air-dry unless IFU instructs otherwise.
6. Dispose of wipes and gloves as clinical waste and perform hand hygiene.
7. Record cleaning if your unit uses logs (common in POCT programs).

If a blood spill occurs on or inside the device, follow the facility spill procedure and the manufacturer’s guidance; internal contamination may require taking the device out of service.

Medical Device Companies & OEMs

Manufacturer vs. OEM (Original Equipment Manufacturer)

In medical technology, the “manufacturer” is the company that takes responsibility for the finished medical device—its intended use, labeling, quality system, and post-market support. An OEM (Original Equipment Manufacturer) may produce components (such as sensors, cartridges, boards, pumps) or even an entire analyzer that is then sold under another company’s brand.

OEM relationships can matter for hospitals because they may influence:

• Parts availability and service pathways (who can repair what, and how quickly).
• Software/firmware update cycles and cybersecurity patching responsibilities.
• Consumable sourcing (single-source cartridges vs multiple sources, which can affect supply resilience).
• Support continuity if product lines are rebranded, acquired, or discontinued.

Hospitals and procurement teams often ask about OEM dependencies during due diligence, especially for high-volume POCT programs where downtime has immediate operational consequences.

Key Takeaways and Practical Checklist for Point of care blood gas analyzer

• Treat the Point of care blood gas analyzer as a governed POCT system, not a standalone gadget.
• Verify two patient identifiers before sampling and before accepting results.
• Prefer barcode workflows to reduce wrong-patient and wrong-chart errors.
• Confirm the analyzer shows “ready” status before running patient samples.
• Check cartridge/cassette type, expiration date, and storage conditions every time.
• Do not run patient testing when required QC is missing or out of range.
• Learn which parameters are measured versus calculated on your device model.
• Record collection time when policy requires it and interpret delays cautiously.
• Minimize air exposure because bubbles can alter gas measurements.
• Mix samples appropriately to reduce clotting and measurement artifacts.
• Avoid using compromised samples; recollect when integrity is doubtful.
• If results are implausible, pause and verify before acting.
• Repeat testing with a fresh sample if sample handling errors are suspected.
• Know your unit’s policy for critical result communication and documentation.
• Ensure results transmit to the EHR; fix connectivity issues promptly.
• Use PPE and sharps safety practices every time blood is handled.
• Dispose of needles and syringes immediately into approved sharps containers.
• Keep a spill kit and approved disinfectants near the testing area.
• Clean high-touch surfaces routinely and after visible contamination.
• Never spray liquids into vents, ports, or cartridge bays unless IFU allows.
• Document errors, repeats, and corrective actions according to policy.
• Report near misses to improve systems, not to assign blame.
• Standardize device placement to reduce workflow variation across units.
• Maintain par levels of cartridges and QC materials to prevent downtime.
• Track lot numbers when required to support recalls and investigations.
• Clarify who owns QC, training, maintenance, and connectivity in your facility.
• Engage biomedical engineering early for preventive maintenance scheduling.
• Evaluate total cost of ownership, not just instrument purchase price.
• Confirm local service coverage and response times during procurement.
• Plan for power stability and backup strategies in critical care areas.
• Train for human factors: alarms, distractions, and time pressure increase errors.
• Use short, unit-level checklists for high-acuity environments.
• Align POCT policies with laboratory oversight and clinical governance.
• Verify units (mmHg vs kPa) to prevent interpretation mistakes.
• Do not assume all analyzers are configured the same across departments.
• Keep operator competency current and use access controls when available.
• Escalate repeated device errors to biomedical engineering without delay.
• Stop using the analyzer if QC fails repeatedly or contamination is suspected.
• Treat surprising results as a trigger to check pre-analytics first.
• Build a culture where “slow down to be safe” is acceptable in POCT.
